From 19th to 22nd July the Chinese number one Ding Liren, with a rating of 2778 currently number eight in the world, and Russian grandmaster Alexander Grischuk, with a rating of 2747 currently number 18 in the world, played a four-game match in Wenzhou, China. Grischuk won the first game from a worse position and Ding Liren did not manage to equalise the score in the following three games. Grischuk won the match 2.5-1.5.
It seems like mini-matches are a thing right now. In May, Ding Liren played Wesley So in a 4-game mini-match as well. Then, more recently, there was the Biel Chess Festival 2016 and Gelfand vs Inarkiev Match 2016.
